We do this using arccos or cos-1 (which mean the same thing: inverse cosine). But then we must do this to both sides of the equation: cos-1 (cos(C)) = cos-1 ( 0.8375 )C = cos-1 (0.8375) **When you use a calculator for trigonometric functions, you really have to pay attention to whether you are in degrees or radians (or gradians).

The Law of Cosines is very handy, too, and it is for arbitrary triangles. In words, The measure of a side of a triangle is the square root of the quantity: the sum of the squares of the other two sides less twice the product of those sides and the cosine of the enclosed angle. There is no ambiguous case for the Law …

If we assume CO2 is a simple gas we can apply Henry’s law that describes the equilibrium between vapor and liquid. Thus: pCO2 = K . xCO2 . where pCO2 is the partial pressure of the gas in the bulk atmosphere (Pa), K is a constant (Pa) and xCO2 is the equilibrium mole fraction of solute in liquid phase.

3² = 4² + 6² -2*4*6 cos A where A ≈ 26.4 ° If we use the Law of Sines (short side first), we obtain 3/sin (26.4°) = 4/sinB or B=36.4 and C=180°-36.4°-26.4° ≈ 117.2 ° When using the Law of Cosines use the longest side first to detect any obtuse angle, and then use the Law of Sines freely.
